Mr. Konrad Lorentz 2 Report post Posted December 7, 2016 Dear Ken, did you installed the vmware tools in your ubuntu? sudo apt-get install open-vm-tools open-vm-tools-desktopThe problem seems to be related to the correct gpu driver. If you have further problems (after installing the vm-tools), submit the out put of glxgears glxgears > glx.txtMaybe interesting for further reading: http://www.mesa3d.org/vmware-guest.html RegardsKonrad Share this post Link to post Share on other sites
